Start by removing mice that are already inside and then close the openings they used to enter in the first place. You can further deter rodents by reducing access to food and shelter.
When rodents feel that first cold snap, they start looking for small weaknesses in houses. Gaps that didn’t matter in summer suddenly become useful to them when temperatures drop. Garages, basements, attics, crawl spaces, and wall cavities are all great places for them to hide until the weather warms up again.
You can start by looking for signs that mice are already inside. The classic warning signs include droppings and gnaw marks, neither of which are subtle. Mysterious holes in bags of food or seed are another. If you hear scratching after dark in your walls, that can often be rodents moving around. Likewise, if you find shredded insulation or paper in seemingly random places, that might be rodent nesting material.
If you have mice, you need to get them out first. You don’t want to seal gaps and seal rodents inside in the process. Once you do that, you can look for how they got inside. Common sources of trouble include gaps around doors and windows, utility line penetrations, foundation cracks, vents, and soffits. Repair damaged screens and weatherstripping when you find them and seal up any openings with chew-proof materials.
After doing that, the next step is to make your property less rewarding. Seed and pet food need to go in metal or heavy plastic containers. Clutter in garages and basements should be cleared out, especially along walls, so they have fewer places to hide.
By the time you see rodents in your home, that can indicate an established infestation. If that’s the case, call a professional. It’s very hard to fix this on your own.
